Range of Variables The Range of Variables explains the contexts within which the performance and knowledge requirements of this standard may be assessed. The scope of variables chosen in particular training and assessment requirements may depend on the work situations available |
What types of high performance turf playing surfaces may require construction of soil profiles for turf establishment? | Surfaces may include sites for high performance sports and recreation such as golfing greens, cricket pitches and purpose built sporting facilities. |
What types of construction method may apply to this standard? | Construction methods may include natural or artificial drainage, perched watertable construction method, pure sand construction, and the United States Golf Association (USGA) or modified USGA construction method. |
What enterprise work procedures may apply to this standard? | Work procedures will be based on sound horticultural principles and practices and may include supervisors oral or written instructions, construction program, enterprise standard operating procedures (SOP), specifications, routine maintenance schedules, work notes; product labels and Material Safety Data Sheets (MSDS); manufacturers service specifications and operators manuals; waste disposal, recycling and re-use guidelines; and OHS procedures. |
What soil tests may be undertaken? | These may include tests for pH, salinity, texture and soil type, and surface and sub-surface infiltration rate test. Samples may include plugs and core samples. Test kits may include a dry test, CSIRO kits, EC meters and pH kits. |
Which services and utilities might need to be located on the site? | Services and utilities may include electricity, gas and phone cables, and water source and drainage outlet for planned sprinkler system. |
How might the site history affect construction? | The previous use of the site may influence the nature of construction or require remediation activities, for example, former livestock treatment sites, landfill, residential, manufacturing, etc. |
What OHS hazards may be associated with the construction of soil profiles? | Hazards may include disturbance or interruption of services, solar radiation, dust, noise, soil and water micro-organisms, chemicals and hazardous substances, manual handling, moving machinery and machinery parts, uneven surfaces, and flying objects. |
What OHS requirements may be relevant to this standard? | OHS requirements may include identifying hazards; assessing risks and implementing controls; cleaning, maintaining and storing tools, equipment and machinery; appropriate use of personal protective equipment including sun protection; safe operation of tools, equipment and machinery; safe handling, use and storage of chemicals and hazardous substances; correct manual handling; basic first aid; personal hygiene, and reporting problems to supervisors. |
What safety equipment may be required? | Safety equipment may include signage and barriers. |
What personal protective equipment (PPE) may be required to construct soil profiles? | Personal protective equipment may include hat, boots, overalls, gloves, goggles, respirator or face mask, face guard, hearing protection, sunscreen lotion and hard hat. |
What surveying equipment may be required? | Surveying equipment may include automatic level, laser level, dumpy level, Cowley level, staff, boning rods, pegs, notebook, pencil and calculator. |
What should be included in plans for the new construction profile? | Plans should include contours, cross-section and profile, and will be based on survey and other research conducted in preliminary phases of the project. |
What features may be included in site and construction plans? | Features may include permanent fixtures, buildings, site aspect, shade, trees and tree roots. |
What structures may the base design include? | Structures may include a one way fall, a rooftop, multiple rooftop or V inverted saucer design. |
What irrigation systems may be relevant to this standard? | Irrigation systems may include tow lines, trailing irrigation, pop-ups, automatic, sprinkler, spray, drip, and hand held hose. |
How may soil amendment quantities be measured? | Measuring techniques may include scales, package size, trucks and volume. |
What materials may be required for the construction of soil profiles? | Materials may include rootzone, irrigation and drainage materials, and soil amendments such as gypsum, lime or zeolite, artificial fibre, organic matter, mineral fertiliser, turf grids, lock sand and fibre turf. |
What soil amendments might be applied? | Soil amendments may include organic matter, zeolite, dolomite, turf starter, and fertiliser. |
What factors may the finishing soil surface incorporate? | Factors may include matching levels of soil with the required final levels, aligning the surface with pegs, and ensuring that no depressions exist and the area is consolidated. |
What tools, equipment and machinery may be required? | Excavation tools, equipment and machinery may include hand tools such as rakes, shovels, spades, wheelbarrows and hoses, and machinery such as bobcats, ditch witches, backhoes, front-end loaders, graders, trucks, hydraulic trailers, and tractors and 3-point linkage equipment. |
| |
What environmental implications may be associated with the construction of soil profiles for high performance turf playing surfaces? | Construction may have beneficial environmental impacts where drainage and irrigation reduce excess water, nutrient and chemical flow into the external environment, including natural waterways, or enable recycling of water run-off thus minimising the draw on water resources. Beneficial impacts may also result from the construction of a soil profile with more efficient water and nutrient utilisation than the original soil profile of the site. Detrimental environmental impacts may arise where surface construction activities produce excess noise, dust or water, or the drainage and irrigation systems do not optimise water use because of incorrect installation or design faults, such as irrigation overspray or inefficient drainage. Where new sites are established for sporting enterprises, the interruption of native corridors and degradation of the ecosystem edge may compromise existing native ecosystems. |
| |
How may a clean and safe work area be maintained? | Tasks may include disabling unused tools, equipment and machinery and storing neatly out of the way of construction activities; safely storing materials on site; using signage and safety barriers during and removing after construction activities are completed; and swiftly and efficiently removing and processing debris and waste from the work area. |
What services may need to be located? | Services may include water supply, gas, power (electricity), telecommunications, irrigation, stormwater and drainage. |
What drainage systems may be relevant to this standard? | Drainage systems may include earthenware, PVC, surface, sub-surface, spoon, agricultural, strip, aggregate, pits, mole plough, sand slit and sub-surface cultivation. |
